Mothers’ complaints that ‘pregnancy makes you old’ were true.
Research has shown that pregnancy can accelerate biological aging in women.
The British daily Guardian reported on the 8th (local time) that scientists at the Mailman School of Public Health at Columbia University in New York, USA, investigated the impact of pregnancy on aging and published it in the scientific journal Proceedings of the National Academy of Sciences (PNAS).
Researchers conducted a long-term, continuous study of the reproductive history and DNA samples of 1,735 young people (825 women, 910 men) in the Philippines.
The biological age of the experiment participants was calculated using the ‘epigenetic clock’, a genetic tool for estimating biological age.
The results showed that a woman’s pregnancy was associated with 2 to 3 months of biological aging, and that women who had more pregnancies during the 6-year follow-up period showed faster biological aging during that period.
The researchers found that the relationship between pregnancy and biological aging held true even after taking into account socioeconomic status, smoking, genetic variation, and the participants’ surroundings.
On the other hand, men of the same age group in the same health survey showed no correlation between increased biological aging and the number of pregnancies.
Callan Ryan, a researcher at Columbia University’s Center on Aging and senior author of the study, said, “The results suggest that pregnancy accelerates biological aging, and that this effect is most evident in young, highly fertile women.”
He said, “Most of the reported pregnancies occurred in late adolescence when women were still growing,” and added, “It will be especially difficult for growing mothers if various supports, including medical services, are lacking.”
“We still have a lot to learn about the role of pregnancy and other aspects of reproduction in the aging process,” he said. “We still have a lot to learn about the role of accelerated epigenetic aging in a given individual, and to what extent it will affect poor health or increased mortality decades later.” “I don’t know,” he added.
